Measurements on I/Q-based data
The I/Q Analyzer application ( not Master ) in MSRA mode can also perform measure-
ments on the captured I/Q data in the time and frequency domain.
The measurements are configured using the same settings as described here for the
Spectrum application.
The results, however, may differ slightly as hardware settings are not adapted automat-
ically as for the Spectrum application. Additionally, the analysis interval used for the
measurement is indicated as in all MSRA applications.
For more information see the R&S
FSW MSRA User Manual.

7.1 Basic Measurements
Basic measurements are common sweeps in the time or frequency domain which pro-
vide an overview of the basic input signal characteristics.
If no other measurement function is selected, or if all measurement functions are
switched off, the R&S
FSW performs a basic frequency or time sweep.
After a preset, a frequency sweep is performed.
Use the general measurement settings to configure the measurement, e.g. via the
"Overview" (see
Chapter 8, "Common Measurement Settings" , on page 356).
